I’m assuming that these are the same types of HWH slides I have in my coach… lol, probably not… In the HWH panel I removed EVERY single fuse (have to unscrew the top smaller screws so that the boards will tilt out(if they don’t tilt out only you are doing more work than needed), cleaned, put dielectric grease (this is debatable) and checked continuity. That solved a LOT of the issues… please keep us in the loop here! The other thought was that once you get electric to the slide for sure I had to reset the hydraulic pressure ‘knob’ in the front bay so just enough pressure was applied to get the rear to slide out (since it is the farthest away), the front takes care of itself.
Another thought is to have the engine running and have GREAT engine batteries - the slides run on the ENGINE batts (at least mine do…)
